CSR2512A0R015F Equivalent & Substitute Parts

Part Overview

The CSR2512A0R015F is a 15 mOhms ±1% 2W chip resistor in 2512 (6432 Metric) package manufactured by Riedon. This current sense, non-inductive metal element resistor operates across -55°C to 170°C and is ROHS3 compliant. The part is classified as obsolete, making identification of suitable equivalent and substitute parts essential for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the CSR2512A0R015F is determined by the following allowable parameters:

• Resistance value: 15 mOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Package / Case: 2512 (6432 Metric) (exact match required)
• Composition: Metal Element (exact match required)
• Features: Current Sense, Non-Inductive (exact match required)
• Operating Temperature Range: -55°C ~ 170°C (minimum requirement)
• RoHS Status: ROHS3 Compliant (minimum requirement)

Power rating may be increased from 2W to 3W as an upgrade path, provided all other electrical and mechanical parameters remain compatible. Packaging format (Tape & Reel, Cut Tape, or Digi-Reel) does not affect electrical equivalence.

Parameter Comparison

Engineering Selection Recommendations

CSR2512C0R015F serves as a direct upgrade substitute with identical electrical specifications and increased power rating (3W vs. 2W). Both CSR2512A0R015F and CSR2512C0R015F are obsolete; however, CSR2512C0R015F maintains the same series designation and temperature coefficient specification.

CSRL3-0R015F1 is the recommended long-term substitute. This part is active in production, ensuring sustained availability. It maintains all critical electrical parameters (15 mOhms, ±1%, Metal Element, Current Sense, Non-Inductive) and mechanical compatibility (2512 package, -55°C ~ 170°C operating range). The 3W power rating provides additional thermal margin. Temperature coefficient is not specified for CSRL3-0R015F1; designs dependent on the ±50ppm/°C specification should confirm compatibility with the manufacturer.

All three parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard handling and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can CSR2512C0R015F directly replace CSR2512A0R015F?

A: Yes. CSR2512C0R015F is electrically and mechanically equivalent with identical resistance (15 mOhms), tolerance (±1%), package (2512), and operating temperature range (-55°C ~ 170°C). The increased power rating (3W vs. 2W) is a non-breaking change. Both parts are obsolete.

Q: Is CSRL3-0R015F1 a suitable long-term replacement?

A: Yes. CSRL3-0R015F1 meets all electrical and mechanical requirements: 15 mOhms ±1%, 2512 package, Metal Element composition, Current Sense non-inductive features, and -55°C ~ 170°C operating range. CSRL3-0R015F1 is active in production, providing supply continuity. The temperature coefficient is not specified; confirm with the manufacturer if ±50ppm/°C performance is critical to your application.

Q: Does packaging format affect substitution?

A: No. Packaging format (Tape & Reel, Cut Tape, Digi-Reel) does not affect electrical or mechanical equivalence. Selection should be based on procurement and assembly requirements.

Q: Are all three parts ROHS3 compliant?

A: Yes. CSR2512A0R015F, CSR2512C0R015F, and CSRL3-0R015F1 are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the key difference between the three parts?

A: CSR2512A0R015F and CSR2512C0R015F differ only in power rating (2W vs. 3W) and are both obsolete. CSRL3-0R015F1 offers the same electrical performance with 3W power rating and active production status, making it the preferred choice for new designs and long-term supply assurance.
